scnnnn ATTACHMENT r03 wINDow-sAsHEs.

Application filed August 3, 1914. Serial No. 854,747.

To all whom it may concern:

Be it known that I, RAYMOND H. BANNING, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Screen Attachments for WVindow-Sashes, ofwhich the following is a specification. H

The present invention relates to improvements in combined balanced sashes and screens, wherein a screen is employed which is secured to the sash and mounted on a weighted roll, whereby the screen will unroll and roll up as the sash connecting the same is raised or lowered. 7

My invention has for its principal objects to provide a structure of the class described, wherein the screen mounting roller is removable from its pocketand is also detachable from the pulley weight shaft; to provide a device employing but a single pulley cord shaft thereby dispensing with one and reducing the cost of manufacture, and one which is adapted for installation in the form of frame now universally inuse.

With the above mentioned'and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings, andipointed out in the claims hereto appended, it being understood that various changes in theform, proportion, size and minor details of construction within the scope of the. claims maybe resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

To more fully comprehend the invention, reference is directed to the accompanying drawings, wherein Y Figure l is a front view of my invention in section, as taken on line 1-1 of Fig. 2. Fig. 2 is a sectional view taken on line 2-2 of Fig. 1, looking in the direction of the arrow. Fig. 3 is a view in detail of the securing connection carried by the end of the screen for attachment to the sash. Fig. 4 is a view taken on line 4a of Fig. 1, disclosing the means for securing the shaft in the screeen supporting roll.

Referring more particularly to the drawings wherein like characters of reference indicate corresponding parts throughout the several views, the numeral 1 designates a window frame or casing having the side Specification of Letters Patent.

members or stiles 2 and 2 betweenwhich slides the sash 3 of the usual construction.

Mounted in a pocket 4 in the head or upper portion of the frame or casing is a screen roller 5 carrying at one end a plate 6,. which in turn carries a journal 7 which isreceived in a bearing plate 8 secured to the inner face of the stile 2. The opposite end of the roller 5 is formed centrally with a longitudinally extendingxbore in which is received the end 6 of a-,suitable shaft 7,

which extends through a cut-out portion 8 in the stile 2 and projects into the upper end of a box 9 in the frame or casing 1. The shaft 7 carries on its end projected into said box a. reel'10, to which is attached one end of a cord 11 carrying at its lower end a weight 12 which is of a sufficient size to approximately equalize the weight of the sash. The shaft 7 is formed with an annular groove 13 which rests in a suitable cutout portion in a bearing plate lt secured to the inner face of the stile 2 adja cent the cut out portion 8. A retaining plate 15 slotted as at 16 is adapted for attachment to the end of the screen roll 5 tom pieces 18 of the pocket 1, the said bottom pieces being slidably' fitted in place, as in Fig. l, and being spaced apart-to form 'a slot or opening19 between the same, as in Fig. 2.

Wound on the roller 5, in a direction opposite to the wind of the cord 11, and secured at one end thereto, is the screen 20, which is of a width to overlap the edges of the dividing beads 21 and operates through the slot or opening 19. The lower edge of the screen is secured in any suitable manner to the attaching bars 217 through the opposite ends of which extend the turn bolts 22 formed on one end with a finger piece 23, and provided at their opposite end with a shank portion 23 carrying the laterally extending arms 24.

Secured over suitable spaced recesses 25 in the upper rail 26 of the sash 3 are plates 27 formed with vertically extending open topped slots 28 provided on their side edges with the inturned flanges 29 which terminate short of the lower end of the slot. In at taching the screen to the sash, the bolts 22 are turned so that the arms 24 lie in a vertical plane, at which time they are inserted in the upper end of the slots 28 and are drawn downwardly thereinto to a point below the flanges 29, and are turned so that the arms 24: will lie in a horizontal plane,

as in Figs. 2 and 3, and the attaching bars.

21 carrying the screen 20 will be detachably locked to the sash rail 26.

When it is desired to remove the roller from its pocket, it is only necessary to re move the bottom pieces 18 of the pocket, detach the lower end 0f the screen from the sash, raise the shaft 7 from its bearing and pass the end of the roller through the cut out portion 8, which will permit the opposite end of the roller to be inclined downwardly and the roller together with the sash cord and weight to be removed from the pocket. 7

It will be apparent that I have provided a screen structure which will prevent the entrance of flies or insects into a room when the sash is lowered; one constructed in such manner as to require but a single sash weight; one having a simplified form of support and attachment for the reel supporting shaft, and one which is simple in construction, and may be employed in connection with the type of frame now universally in use.

Having thus described my invention what I claim is 1. In a device of the class described and in combination with a casing and sliding sash, the same comprising a screen roller, a supporting shaft extended from each end of said roller and cooperating with said casing, a screen carried by'said roller, means for detachably securing the screen to the sash, one of said shafts being received in said roller and carrying on its exposed end a reel for a sash weight cord, means coacting with said last mentioned shaftand detachably secured to the end of said screen roller for securing the shaft thereto and for looking said shaft to rotate therewith, and bearings for detachably supporting said shafts.

2. In a device of the class described and in combination with a casing and sliding sash, the same comprising a screen roller rotatably mounted in said casing above said sash, a supporting shaft extended from each end thereof and cooperating with said casing, one of said shafts being received at one end in said roller and carrying at its opposite end a reel for a sash weight, said shaft formed within its length with an annular groove and also provided with oppositely disposed transverse slots, a plate provided with a slot adapted to be received in said transverse slots and for securing to the end of. said roller for locking said shaft to rotate therewith, and a bearing for each of said shafts, one of said. bearings formed with a substantially V-shaped open'topped recess for receiving the annular groove in said shaft, a screen carried by said roller, and means for detachably securing the lower end of said screen to said sash.

3. In a device of the class described. and in combination with a casing and sliding sash, the same comprising a screen roller rotatably mounted in said casing above said sash, supporting shafts extending from said roller and rotatable therewith, one of said shafts carrying a reel for a sash weight, a screen carried by said roller, attaching bars carried by the lower end of said screen, headed securing bolts extended through said attaching bars and rotatably mounted therein, and a plate secured to the rail of said sash and formed with an open topped slot provided with inturned flanges for receiving the headed end of said locking bolt.

In testimony whereof I have signedmy name to this specification in the presence of two subscribing witnesses.

RAYMOND H. BANNING.
